Definitions

  • the activating mechanism of intercept valves associated to the guns generally comprises a control lever hinged to the handle grip of the gun and destined to open the intercept valve. If the intercept valve is located in proximity of the front portion of the handle grip, the lever is generally rotatably hinged at a pivot, which is also situated close to the front portion of the handle grip.
  • the front lever hinge is advantageous from an ergonomic point of view since it is easier for the human hand to squeeze a lever diverging from a grip at a front part of the hand, i.e. starting from the position of the index finger, rather like when using a brake lever on a bicycle.
  • the prior art has placed the control lever, in these cases, in the same posterior part of the handle grip.
  • the main aim of the present invention is to provide an activating mechanism for an intercept valve which overcomes the mentioned drawbacks.
  • An important aim of the present invention is to provide an activating mechanism for an intercept valve which preserves the high performance and good ergonomic characteristics of mechanisms having the control lever hinged to the front part of the grip of a spray gun, even where the intercept valve is located in a best position therefor, i.e. in the posterior portion of the handle grip.
  • a further important aim of the invention is to provide an activating mechanism having a simple structure and being reasonably economical to produce.
  • a further aim is to provide a highly-reliable activating mechanism having good resistance characteristics with regard to the stress it is placed under.
  • the activating mechanism is associated to the handle grip 2 of a spray gun 3 provided with an intercept valve 4, advantageously having a ball obturator as described in a further patent application of the present applicant.
  • the intercept valve 4 is arranged at a posterior portion 2a of the grip 2 and comprises a control element for changing the valve from closed to open and to closed once more, constituted by a pusher element 6 laterally disposed with respect to the liquid flow direction and destined to press on the ball obturator 5 in order to detach it from an annular seating 7 on which the ball obturator 5 rests when the intercept valve 4 is in the closed position.
  • the activating mechanism 1 comprises a control lever 8 which can be pressed by a user's fingers and is rotatably constrained at a first end thereof 8a to a pivot 9 arranged in proximity of a front portion 2b of the grip 2.
  • the dimensions, conformation and position of the hinge of the control lever 8 are established mainly on the criterion of ergonomics.
  • An activating lever 10, acting on the pusher element 6 of the intercept valve 4, exhibits a first end portion 10a constrained rotatably to a hinge pivot 11 arranged in proximity of the back portion 2a of the grip 2 and a second end portion 10b constrained to the control lever 8. More precisely, the control lever 8 exhibits a groove 8b which houses the second end portion 10b of the activating lever 10, allowing sliding contact of the activating lever 10 with the control lever 8.
  • At least one elastic element can be provided, preferably a spring 14 which acts, for example, on the activating lever 10.
  • the spring 14 is interpositioned between the activating lever 10 and the handle grip 2.
  • the spring 14 may not be necessary.
  • the invention has important advantages.
  • the activating mechanism of the invention exhibits a simple structure, which is nonetheless sturdy, highly reliable and relatively inexpensive to manufacture.
